V2 Suit

Working in space is not only disorienting, it’s also unhealthy. That’s because muscles atrophy in zero gravity — mainly because your body thinks you don’t need them. According to NASA, muscles that fight gravity, like your calves, can lose up to 20% of their mass in space. The Variable Vector Countermeasure Suit (V2 Suit) hopes to use gyroscopes and accelerometers to track the position and orientation of different body parts and add “viscous resistance” to mimic the sensation of gravity and keep astronauts’ muscles from withering away.
